Yeah I agree. He just didn't have enough to do, there was no space for him to break into a full stride with Superman or Clark. And the scenes he is in, he gets so little dialogue. After noticing this, its really frustrating watching each scene go by so little contribution by Superman/Clark. He gets no good dialogue. Or we get really long scenes of Lex and a train set, or uneccesary scenes with Lois and Richard or the kid, just eating away at the run time. I don't even think Routh's take on the character was forgettable, it was the role. Any other actor would have had the same problems. It's not the films only problem by far, but it's one of the bigger ones.
